The green star at the lower right side of Mawile's profile signifies that you are very lucky - you have caught a Hidden Ability Mawile, as usually its abilities are Intimidate and Hyper Cutter, but you have obtained a Sheer Force Mawile.

On the other hand, I have no idea what the number stands for or means.
